Simplifying (m + -1) * x2 + -4x + -1 = 0 Reorder the terms: (-1 + m) * x2 + -4x + -1 = 0 Reorder the terms for easier multiplication: x2(-1 + m) + -4x + -1 = 0 (-1 * x2 + m * x2) + -4x + -1 = 0 Reorder the terms: (mx2 + -1x2) + -4x + -1 = 0 (mx2 + -1x2) + -4x + -1 = 0 Reorder the terms: -1 + mx2 + -4x + -1x2 = 0 Solving -1 + mx2 + -4x + -1x2 = 0 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '1' to each side of the equation. -1 + mx2 + -4x + 1 + -1x2 = 0 + 1 Reorder the terms: -1 + 1 + mx2 + -4x + -1x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + mx2 + -4x + -1x2 = 0 + 1 mx2 + -4x + -1x2 = 0 + 1 Combine like terms: 0 + 1 = 1 mx2 + -4x + -1x2 = 1 Add '4x' to each side of the equation. mx2 + -4x + 4x + -1x2 = 1 + 4x Combine like terms: -4x + 4x = 0 mx2 + 0 + -1x2 = 1 + 4x mx2 + -1x2 = 1 + 4x Add 'x2' to each side of the equation. mx2 + -1x2 + x2 = 1 + 4x + x2 Combine like terms: -1x2 + x2 = 0 mx2 + 0 = 1 + 4x + x2 mx2 = 1 + 4x + x2 Divide each side by 'x2'. m = x-2 + 4x-1 + 1 Simplifying m = x-2 + 4x-1 + 1 Reorder the terms: m = 1 + x-2 + 4x-1
